Chelsea Harvey covers climate science for Climatewire. She tracks the big questions being asked by researchers and explains what's known, and what needs to be, about global temperatures. Chelsea began writing about climate science in 2014. Her work has appeared in The Washington Post, Popular Science, Men's Journal and others.
Global efforts to tackle climate change rest on a common goal: to keep the planet's temperatures from rising beyond dangerous thresholds. But what if the gases that come from cars and power plants are harming the planet themselves, even without the warming they cause?
Climate change is on track to become the world's greatest threat to biodiversity in the next half-century, topping human land-use change as the main driver of species loss among vertebrate land animals, new research suggests.
World leaders have about two decades before overshooting their most ambitious climate goal of preventing temperatures from rising more than 1.5 degrees Celsius. It doesn't sound like much time to turn things around, but it's substantially more wiggle room than some previous estimates have suggested.
Wetlands are some of the most carbon-rich ecosystems on Earth — and preserving or restoring them, some experts say, can sequester carbon dioxide and help mitigate climate change. It's a strategy known as "blue carbon."
The Antarctic ice sheet lost a whopping 3 trillion tons of ice between 1992 and 2017, scientists announced this week.
